WebJun 21, 2024 · Graph Backdoor. One intriguing property of deep neural network (DNN) models is their inherent vulnerability to backdoor attacks – a trojaned model responds to … WebGraph Trojaning Attack (GTA) which also uses subgraphs as triggers for graph poisoning. But unlike Subgraph Backdoor [50], GTA learns to generate adaptive subgraph structure for a specific graph. Different from Subgraph Backdoor and GTA, GHAT learns to generate pertur-bation trigger, which is adaptive and flexible to different graphs. Fig. 3

WebJan 18, 2024 · The backdoor path criterion is a formal way about how to reason about whether a set of variables is sufficient so that if you condition on them, the association between X and Y reflects how X affects Y and nothing else. This strategy, adding control variables to a regression, is by far the most common in the empirical social sciences.

Webgraphs, backdoor attacks inject triggers in the form of sub-graphs [18]. An adversary can launch backdoor attacks by manipulating the training data and corresponding labels. Fig. 2 illustrates the flow of a subgraph-based backdoor attack against GNNs. In this attack, a backdoor trigger and a target label y t are determined. WebJan 18, 2024 · 1.

WebClause (iii) say that Xsatis es the back-door criterion for estimating the e ect of Son Y, and the inner sum in Eq. 2 is just the back-door estimate (Eq. 1) of Pr(Yjdo(S= s)). So really we are using the back door criterion. (See Figure 2.) Both the back-door and front-door criteria are su cient for estimating causal
